style(ui): counters on labels sit right after the word

The counter hung at the label's right edge with a fixed 12 px gap, so
two-digit numbers covered part of the last letter. It now follows the
word in the text flow (position="text"): only its ring overlaps, the
same for any number of digits, and wide numbers widen the tab.
